How SceneMixer marks its output
SceneMixer (scenemixer.com), an AI short-drama generator, states its marking in its terms of service as well as on its product pages, and it names both layers: a visible label, and an invisible, compression-resistant watermark or content credential that is never removed. As of 2026-10-13.
| Field | What the vendor's pages state |
|---|---|
| Free tier | Corner badge at delivery, on by default |
| Paid tier | Off for paid members; the invisible layer stays |
| User toggle | Plan benefit, a switch for paid members |
| Machine-readable marking | Invisible watermark or content credential |
Inclusion rule. Fields are the same four for every generator on this site; a field the vendor does not publish is recorded as not documented rather than inferred from how the product behaves. Order. Fixed field order, identical on every generator page.
1What the terms state
Section 05 of the terms says output carries a two-layer mark: a visible label plus an invisible, compression-resistant watermark or content credential, applied under rules the terms name, China's deep-synthesis provisions and Article 50 of the EU AI Act. Removing the visible label is an optional paid feature, available only where the user's own use lawfully allows it, and the invisible layer is never removed.
The product pages describe the visible half in practice: a small corner badge applied at delivery by default, which paid members can switch off for later renders from a toggle beside the model selector.

2What stays on the file
The layer a viewer never sees is the one the terms make permanent. That puts this entry with the few here that state a machine-readable signal, and its terms go further than most by saying the signal is never removed, on any plan. Its compliance guide adds the publisher's side: keep whatever content credentials the tool writes, because re-encoding through an editor that strips metadata can remove them.
The terms publish no reader and no field list for the invisible layer, so a downstream party cannot yet check it the way SynthID or Content Credentials can be checked. That is the part still to be published.
